IMPROVEMENT IN BED-WARMERS.

Specification forming part of Letters Patent No. 146,577, dated January 20, 1874; applicationfiled December 20, 1873. i

proved bed'warmer, Fig. 2 a top view, and

Figs. 3 and 4, respectively, vertical central and horizontal sections on the lines so as and c 0, Figs. 2 and 1, of the same.

Similar letters of reference indicate corre- My invention relates to improvements in bed-warmers for the use of invalids and others, which may be conveniently placed between the sheets for warming them readily, filled and tightly closed, without 1noistening .the emptied without retaining any water therein. My invention consists of i a fiat circular metallic bed-warmen to be filled with hotwater, which is provided with a screwplug fitting hermetically into a screw-seat, which is arranged with notches for allowing every drop of water to be extracted from the inside, both plug and seat projecting to the inside of the pan, being flush with the outer surface.

In the drawing, A represents the body of the bed-warmer, which is made of fiatlens shape, so as to be slipped conveniently under the sheets without lifting the bed-cover and avoiding drafts of cold air to enter with it. Thebed-warmer is made of copper, tin, or other suitable meta], attached to a suitable handle, B, and provided at its top part with a central screw-plug, O, which fits hermetically into a screw-seat, 0, set flush with the outer, and projecting beyond the inner, surface of the warmer A. A ring, D, is loosely connected to screw-plug O, by which the same is tightened or loosened, dropping then sidewise over the top of the pan without interfering with the bed-cover in introducing or withdrawing the warmer to and from the sheets. The bedwarmer is filled with hot water, the screwplug screwed in till it closes tightly. in the socket, so that the vessel retains thereby the heat much longer and prevents the escape of steam or water, and the consequent moisten ing or wetting of the sheets.

The flat bed-warmers hitherto in use retain .always a quantity of water after use, which may only be. got rid of by evaporation, causing oxidation and the rapid wearing out of the bed-warmer. To avoid these defects and extract every drop of the cooled-off water after the warmer has been used, so as to allow refilling or storing away, I provide that part of screw-seat or socket C which projects below the inner surface of the vessel, with one or more vertical slots or notches a, by which the water may entirely pass out of the warmer,

as the concave sides carry every drop toward the screw-seat and thence -to the outside of the vessel. The bed-warmer is then easily dried after use, and -made thereby ,more durable, being also less annoying in its use, as the out-v side projecting parts of plugs and similar stoppers, which caught in the bed-clothes and disturbed the same, are done away with, making the bed-warmer more serviceable in every respect.

- Having thus-described my invention, I claim as new and desire to'secure by Letters Patent A hollow lens-shaped metallic bed-warmer, provided with a handle of suitable length and a central screw socket and plug, which projects to the inside of the bed-warmer, the former having vertical slots or notches extending up to the inner surface of the pan, for the purpose hereinbefore described.
